Microbial Fuel Cell: Simultaneous Bioremediation and Energy Recovery Technology

Microbial fuel cells (MFCs) are a promising technology for producing electricity from a variety of materials, including natural organic matter, complex organic waste, and renewable biomass, and can be advantageously combined with wastewater treatment applications. For this reason, it represents a superb option for a long-term, eco-friendly renewable energy supply. The current review article discusses about Malaysia's historical energy consumption trend. Following that, Malaysia experienced a revolution in energy-based policies, such as the National Energy Policy 1979, which focuses on the effectiveness of energy supply while minimising negative environmental impacts through the development of new technologies such as MFC technology. In addition, the concept and operation principle of MFC are discussed in this review. This paper focuses on single-chambered and dual-chambered MFC. The performance of MFCs is influenced by the substrate used so the various substrates that are commonly used today are also discussed.
